Sander Battery Platform Acute Angle Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional belt sanders often have an unbalanced weight distribution and battery placement that can make them difficult to maneuver and store, as well as lack a compact design for improved handling and efficiency during sanding operations.
Innovation Solution
The sander features a battery platform oriented at an acute angle relative to the belt drive assembly, with the battery pack supported above the handle and positioned to maintain a lower center of gravity, allowing for easier handling and storage, and a split-housing design for maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery pack is placed in a conventional position on belt sanders, then the sander can be assembled, but the weight distribution becomes unbalanced making it difficult to maneuver and store
Solution Approach 1:
The battery platform is oriented at an acute angle relative to the belt drive assembly plane, positioning the battery pack in a three-dimensional space that optimizes weight distribution. This angular orientation allows the battery pack to be located above the handle while maintaining a lower center of gravity, resolving the contradiction between ease of maneuvering and weight distribution.
Solution Approach 2:
The battery pack is strategically positioned to create a counterbalancing effect. By locating the battery pack above the handle and orienting the platform at an acute angle, the design creates a lower center of gravity that acts as a counterweight, improving maneuverability while maintaining balanced weight distribution throughout the sander assembly.
2Ease of operation
If the sander is designed with conventional battery placement, then the components can be assembled, but the overall design lacks compactness reducing handling efficiency
Solution Approach 1:
By orienting the battery platform at an acute angle rather than parallel to the belt drive assembly, the design utilizes three-dimensional space more efficiently. This angular configuration allows the battery pack to be integrated into the housing structure above the handle, achieving a more compact overall design that improves handling efficiency without increasing the sander's volume.
3Ease of operation
If the battery platform is oriented parallel to the belt drive assembly, then the structure is simple, but the sander becomes difficult to maneuver and store
Solution Approach 1:
The battery platform is oriented at an acute angle relative to the belt drive assembly plane, utilizing three-dimensional spatial arrangement to achieve better weight distribution and maneuverability. This angular orientation, while slightly more complex than a parallel arrangement, optimizes the center of gravity position and overall compactness, significantly improving maneuverability and storability.
Solution Approach 2:
The design employs asymmetric orientation of the battery platform at an acute angle rather than a symmetric parallel arrangement. This asymmetric configuration allows the battery pack to be positioned above the handle, creating an optimized weight distribution that enhances maneuverability while maintaining a compact form factor suitable for easy storage.

AI summary
A sander includes a housing defining a front end and a rear end relative to a direction of travel of the sander on a work surface, an actuator, and a battery platform. The housing supports a motor and has a grip disposed over the motor adjacent the front end and a handle positioned at or adjacent the rear end. The housing further supports a belt drive assembly configured to rotatably support a belt and having a belt plate extending a long a first plane. The actuator is supported by the handle. The battery platform is at least partially supported by and located above the handle. The battery platform defines a battery pack receptacle configured to support a battery pack. The battery platform is oriented along a second plane orientated at an acute angle relative to the first plane.
